Air Pollution and Cancer Risk
WHO classifies outdoor PM2.5 particulate matter as Group 1 confirmed carcinogen alongside tobacco and asbestos. These particles penetrate deep into lung tissue causing DNA damage, inflammation, and mutations over years of exposure. Air pollution accounts for 15% of...
Can Obesity Increase Cancer Risk?
Obesity significantly increases risk for at least 13 cancer types including breast, colon, endometrial, kidney, pancreatic, liver, and esophageal cancers. Excess body fat produces elevated estrogen, chronically high insulin, and sustained inflammation that together...
Tobacco and Cancer Risk Over Time
Tobacco causes at least 16 cancer types and is responsible for 30% of all cancer deaths globally. Risk isn’t triggered by a single cigarette or one pouch of gutka. It builds cumulatively as DNA damage from each exposure accumulates faster than the body’s...
Can Vaping Cause Lung Cancer?
Emerging evidence strongly suggests vaping increases lung cancer risk through DNA damage, oxidative stress, and tumor-promoting inflammation in lung tissue. E-cigarette aerosol contains formaldehyde, acetaldehyde, heavy metals, and nitrosamines at concentrations...
